“This can commonly occur in people with severe chronic obstructive lung disease and asthma. The lorry driver had a full medical and was in generally good health, not intoxicated and was driving within the 50mph speed limit.

“Cough syncope can’t be proved and therefore was based on the “probability” that he lost consciousness by three different medical experts.

“This leaves a massive loophole in the law.

“There are many things that don’t add up and because there wasn’t enough evidence, the Crown Prosecution Service declined taking it to court.

“The petition won’t bring back my dad or change the decision in his case but by signing this petition you could help raise awareness to the Government and stop this happening to other families in the future.”

Phil, 50, worked as a carpenter in the family business, B&B Carpentry along with his brother, David and son Jack.

Harry said: “Jack still goes to work as a carpenter but it is hard for him. Some days he hobbles so my uncle tries to make sure Jack has jobs he can cope with.

“It has affected all of us in so many ways. We just want to make sure nobody else goes through this and uses this loophole. It feels like we haven’t had closure.”

Phil was killed on the A10 near Chittering, on October 7, 2015.

He was driving home to celebrate his daughter’s 21st birthday with his nephew Jack in the passenger seat, who suffered life-changing injuries.

Phil’s younger brother David has criticised the CPS decision not to prosecute after an inquest found truck driver William Abbott didn’t apply his brakes before the crash.

The petition is on Change.org and is called “eliminate cough syncope as an explanation to road traffic collisions.”
